A zone-resolved photoelectron spectroscopy (ZPS) has enabled us to gain thelocal and quantitative information and hence confirm our theoreticalexpectations on the bonding and electronic dynamics at graphite skin with andwithout atomic vacancy defects. The ZPS study has revealed: i) the 1s energylevel of an isolated carbon atom is located at 282.57 eV, which shifts by 1.32eV deeper upon diamond bulk formation; ii) the graphite surface bonds contractby 18% with 165% gain in energy compared with the C-C bond in the bulk diamond;the surface C 1s energy shifts 2.08 eV deeper from the 1s level of an isolatedcarbon atom; and iii) the defect bonds are ~26% shorter and 215% stronger withthe binding energy shift of ~2.85 eV. An additional polarization peak centeredat 1.28 eV below the C 1s level presents when the vacancy is formed. Associatedwith the scanning tunneling microscopy/spectroscopy observations and densityfunctional theory calculations, the ZPS measurements clarify, for the firsttime, that the graphitic Dirac-Fermi polarons at atomic vacancy or graphenezigzag edge arise from the polarization of the unpaired dangling-bond electronsby the undercoordination-induced local densification and quantum entrapment ofthe bonding electrons.
